Jungheinrich ECE 220 Standard Operating Instructions Manual page 79

Ignoring the operation instructions, repair with non-original parts and non authorised
interventions will render the warranty void.
For batteries in classes
protection class during operation must be complied with (see relevant certificate).
1. Commissioning
The battery should be inspected to ensure it is in perfect physical condition.
The battery end cables must have a good contact to terminals, check that the polarity
is correct.
Otherwise battery, vehicle or charger could be destroyed.
The battery has to be charged according to item 2.2
The specified torque loading for the pole screws of the end cables and connectors
are:
steel
M 10 23 ± 1 Nm
2. Operation
DIN EN 50272-3 «Traction batteries for industrial trucks» is the standard which ap-
plies to the operation traction batteries in industrial trucks.
2.1 Discharging
Ventilation openings must not be sealed or covered.
Electrical connections (e.g. plugs) must only be made or broken in the open circuit
condition.
To achieve the optimum life for the battery, operating discharges of more than 60%
of the rated capacity should be avoided (deep discharge).
They reduce the battery life considerable. To measure the state of discharge use only
the battery manufacturer recommended discharge indicators.
Discharged batteries must be recharged immediately and must not be left dischar-
ged.
This also applies to partially discharged batteries.
2.2 Charging
Only direct current must be used for charging. Charging procedures according to DIN
41773 and DIN 41774 must only be applied in the manufacturer approved modifica-
tions. Therefore only battery manufacturer approved chargers must be used. Only
connect the battery assigned to a charger, suitable for the size of battery, in order to
avoid overloading of the electric cables and contacts and unacceptable gassing of the
cells. EPzV batteries have a low gas emission.
When charging, proper provision must be made for venting of the charging gases.
Battery container lids and the covers of battery compartments must be opened or re-
moved.
